Phacotrabeculectomy in Eyes With Uveitic Glaucoma: A Retrospective Case-Control Study.

PRECIS

Phacotrabeculectomy with adjunctive mitomycin C is a good option for the management of coexisting cataract and glaucoma. Strict preoperative control of inflammation and close follow-up are essential in the management of eyes with uveitic glaucoma (UG).

PURPOSE

The purpose of this study was to compare the outcomes of phacotrabeculectomy with adjunctive antimetabolites in the management of patients with UG and patients with primary open-angle glaucoma (POAG).

MATERIALS AND METHODS

A retrospective case-control study of 112 patients with UG and 120 patients with POAG who underwent phacotrabeculectomy with mitomycin C and had a follow-up of ≥12 months between January 2000 and June 2015 was performed. Patients who had undergone intraocular surgery or cyclodestructive procedures earlier were excluded. The primary outcome was intraocular pressure (IOP) control; secondary outcomes included visual acuity and complication rates.

RESULTS

IOP control was similar at the final visit in the UG group (14.52±6.74 mm Hg) and the POAG group (14.39±4.18 mm Hg) (P=0.867). Kaplan-Meier survival analysis showed a cumulative probability of survival (IOP: 6 to 18 with or without medications) in 71% and 77% at the end of 5 years (P=0.094) in the UG and POAG groups, respectively. Visual outcomes were worse in the UG group (0.5±0.68 logMAR units), as compared with the POAG group (0.27±0.47 logMAR units) (P=0.002). Complications such as cystoid macular edema (P=0.025) and posterior capsular opacification (P=0.004) were more common in the UG group. Recurrence of inflammation occurred in 34 eyes (30.04%) in the UG group.

CONCLUSION

Meticulous control of perioperative and postoperative inflammation could have contributed to the favorable long-term outcomes of phacotrabeculectomy in UG, as compared with POAG.
